1. `RTSPFrameSource` captures a resized RGB frame.
2. `ZoneOccupancyDetector` updates per-zone binary occupancy and generic trash-motion count from calibrated ROIs.
3. `TrajectoryTracker` watches zones that just cleared, follows lightweight motion points toward the trash ROI, and emits source-specific `DisposalEvidence` when confidence passes the configured threshold. If the middle of the path is occluded, a segmented source-to-trash track can still emit evidence.
3. `TrajectoryTracker` caches recent source-region motion while a zone is occupied, watches zones that just cleared, follows lightweight motion points toward the trash ROI, and emits source-specific `DisposalEvidence` when confidence passes the configured threshold. If the middle of the path is occluded, a segmented source-to-trash track can still emit evidence.
4. `BatchEngine` processes `Observation(zone_counts, trash_deposit_count, disposal_evidence)`.
5. For pending disposal, matching `disposal_evidence.source_zone_id` confirms `batch_discarded` before generic FIFO `trash_deposit_count` fallback is used.
6. Runtime writes events to `logs/events.jsonl` and diagnostics to `logs/runtime_diagnostics.jsonl`.
